Chapter 5: Advanced Calculations — Advanced Keyboard
The following math functions can be accessed with the use of @ key. To learn the
basic steps of how to access the second function of each key, refer to the section
“Second Function Key” of Chapter 2.
s Enters an arcsine function to be used in a trigonometric expres-
sion.
Example
• Calculate arcsine 1.
@ s 1 E.
c Enters an arccosine function to
be used in a trigonometric
expression.
Example
• Calculate arccosine 0.5.
@ c 0.5 E.
t Enters an arctangent function to be used in a trigonometric
expression.
Example
• Calculate arctangent 1.
@ t 1 E.
